Theoretically, it will definitely be able to remove space garbage, but there are many difficult problems in actual operation.

For example, when improving strong electromagnetic satellites, Chinese engineers proposed to strengthen the armor protection of satellites to resist space garbage flying at high speeds. The problem is that metal can shield the electromagnetic field, so metal armor cannot be used. Only composite materials with the least effect of electromagnetic field attenuation can be used. Similar composite materials are not strong enough to provide effective protection for satellites.

Of course, there is no way to solve it. [bsp;    Some materials scientists proposed that foam materials can be used, that is, after the satellite enters orbit, expanding foam is released on the periphery of the satellite to wrap the entire satellite. As long as it is thick enough, it can block space garbage. All it needs to be done is to increase the launch quality of the satellite. The existing rockets in various countries have sufficient launch capabilities, and at most they can only launch more rockets in a bundled manner.

The problem is that this does not solve another problem.

Even if it can block space garbage, it cannot eliminate the momentum of space garbage. That is to say, after being hit by space garbage, the speed of the satellite will decrease and its orbit will change. If the kinetic energy generated by the impact points to outer space, the problem is not very serious, and it only increases the operating altitude of the satellite. If it points to the earth, it will cause the satellite to lower its flight altitude and then fall into the atmosphere and burn.

According to theoretical calculations, as long as the impact angle is correct, a piece of space waste can cause a strong magnetic field satellite operating in a near-circular orbit of 300 kilometers to fall into the atmosphere within one month. In low-Earth orbit, the frequency of being hit by space waste with a mass of more than one kilogram is once every three days. Obviously, such a fast loss speed is far beyond the ability of China and even all countries. You must know that in these 33 days, a strong magnetic field satellite can recover up to 100 kilograms of space waste. Near-Earth orbit requires nearly 100,000 such satellites to remove all metal fragments in the low-Earth orbit, and its total cost is equivalent to ten times the annual output value of all countries in the world!

Of course, some people have proposed to install a variable orbital motorized engine for strong magnetic field satellites.

The problem is that the variable orbital motor must be externally installed, at least the nozzle must be externally installed. If the nozzle accounts for only five percent of the satellite's surface area, and the possibility of impact is reduced by 80 percent through protection means, there is also a one-percent chance of being hit by space garbage. Because destroying the nozzle only requires space garbage with a mass of more than ten grams, the satellite may be hit by space garbage after an average of about ten days of operation. If the fuel explosion occurs, then the debris generated by a strong magnetic field satellite needs ten same satellites to be cleaned.

The result is that the more satellites are launched, the more space garbage it needs to be cleaned.

This does not include those non-metallic fragments.

If all of this is included, billions of people around the world will have to work for nearly twenty years without eating or drinking to complete this project. If one-tenth of the world's productivity is used to clean up space waste, it will take two hundred years to complete, and the premise is that human productivity will not be reduced by natural disasters.

There is no doubt that this is basically of no operational value.

You should know that even if you ignore it, space garbage in low-Earth orbit will gradually fall into the atmosphere and burn it in the next two to three hundred years.

To put it simply, the aerospace technology mastered by humans is very backward.

At the meeting on February 10, military representatives from all sides admitted that with current aerospace technology, it is difficult for humans to clean up space garbage in low-Earth orbit. The most effective and correct measure is to temporarily stop all cleaning operations and conduct research after a major breakthrough in aerospace technology has made.

The "aerospace technology" mentioned here is mainly power technology.

At that time, whether it was solid rocket engines or liquid rocket engines, they were chemical energy power devices, and their energy utilization efficiency was surprisingly low. Although several major aerospace powers were developing new aerospace means, such as using electromagnetic railguns to send artificial objects into space, major aerospace activities still needed to rely on chemical energy. As for other aerospace propulsion tools, most of them were in the theoretical stage, or in science fiction novels.

Based on the common interests of mankind, China, the United States, Europe and Russia should unite.

Unfortunately, space garbage in low-Earth orbit has no direct impact on human survival, and at most it will slow down humanity's pace into the universe by hundreds of years. Therefore, there are serious differences between China, the United States, Europe and Russia on whether to jointly develop new aerospace propulsion methods.

Both the EU and Russia advocate joint development because this is the most effective way to speed up the development progress.

The United States and China firmly oppose it, believing that this is not necessary for the time being, and that aerospace capabilities are the main pillar of national security after nuclear weapons become history.

The main reason for this is the gap in aerospace technology between Sifang.

It is undeniable that the EU and Russia are both major aerospace powers, but their focus is on developing existing technologies, namely, manufacturing chemical energy rockets. In more cutting-edge fields, the gap between the EU and Russia is very large, while the leading advantages between China and the United States are already very obvious.

For example, the United States was the first to use electromagnetic acceleration for aerospace launch. As early as twelve years ago, American scientists used electromagnetic coil cannons to send a metal rod weighing 20 grams into low-Earth orbit. The United States originally planned to launch a 250 grams microsatellite in the same way in 2040.

Compared with the United States, China's research in the field of aerospace is more cutting-edge.

Of course, it is even more mysterious.

According to the information disclosed later, before 2030, China had conducted in-depth research on the "field energy" technology and regarded "field energy" as the main means of advancement for future aerospace activities. The "field energy" mentioned here mainly refers to the gravity field.

In basic theory, the gravity field is an energy field, which contains very huge energy.

Cosmic scientists have long proposed that visible matter in the universe only accounts for 2% of the total mass of the universe, and 98% are so-called "dark matter". Unfortunately, scientists have not given a clear definition of "dark matter", that is, no one knows what dark matter is.

If dark matter is an ubiquitous gravity field, then the universe is not so empty.

To put it bluntly, if the energy of the gravity field can be used, human space capabilities will be substantially improved, and they will have the ability to enter a wider universe, and they may even overturn Einstein's theory of relativity proposed by relativity and go to other galaxies.

Around 2032, Chinese scientists published related papers and won the Nobel Prize for this.

The problem is that almost all Western scientists scoff at this.

Western scientists do not believe that field energy cannot be used, but believe that field energy is impossible to use until a major breakthrough in basic theory is made.

It can be said that Western scientists have no mistake in their understanding.

The general theory of relativity proposed by Einstein has locked down modern physics. If you want to make a breakthrough, you must not only overturn general theory, but also propose new basic theories. Unfortunately, the research work of basic theories cannot be made by money, and it cannot be done by time, because this is the purest mental labor and cannot even be expressed in written formulas. Under the limitation of the overall intellectual level of human beings, major breakthroughs in basic theory are something that is encountered but hard to find, and are even less swayed by human will.

When it is impossible to guarantee that basic theoretical breakthroughs can be achieved, what is the significance of conducting relevant application research?

To put it bluntly, who knows how to build an atomic bomb before the publication of the theory of relativity?

Of course, before the publication of the theory of relativity, scientists had discovered radioactive elements and discovered mass loss through the half-life period of radioactive elements. It was these discoveries that inspired Einstein and proposed the famous mass-energy formula at a very young age.

It can be seen from this that the objective discovery of natural phenomena is the key factor that contributes to theoretical breakthroughs.

If scientists such as Madame Curie had not discovered radioactive elements, even if Einstein's IQ was surprisingly high, he would probably not have proposed the special theory of relativity.

Western scientists scoff at Chinese scholars precisely because they have not yet observed natural phenomena.

The courage of Chinese scientists to go ahead is also related to the original discovery, namely, the major discovery that strong magnetic fields affect the gravity field. Without this discovery, Chinese scientists, especially physical scientists, would not focus on researching field energy, and would not put so much effort into basic theory.

It is precisely because China is unwilling to cooperate with other countries.

To put it bluntly, if Chinese scientists make major breakthroughs in field energy research, they can surpass scientists from other countries for decades, take the lead in using field energy in space activities, raise human aerospace capabilities to a new height, and completely change human civilization.

Of course, before the great integration of human civilization, any discovery belongs to the country.

As long as the political form of the country still exists, Chinese scientists have no reason to share research results with others. Science has no borders, but scientists have borders. More importantly, such a major scientific research project is absolutely inseparable from national power and must be under the control of the state machine. Even if a scientist is in love with human civilization, it is impossible to surpass the state machine and do things that are contrary to national interests.

After the joint development negotiations broke down, Mu Haoyang returned to China.

Teng Yaohui did not arrange new jobs for him, meaning that he would make some adjustments. After all, he has not been relaxed for a day for most of the past six months. But Mu Haoyang couldn't stay idle at all and was about to tell him that he didn't have to do anything today, and I'm afraid he really didn't know what to do.

Since he was still responsible for the cleaning of space garbage, Mu Haoyang turned his attention to aerospace technology.

Of course, this is not his subjective intention.
